Rain water is known as the purest water in the world, because it still has no additional minerals or dirts abtained from contact with soil or stones. Since ancient time, rain water is believed to have many health benefits in many cultures. There are millions of people drinking rain water troughout the world, mainly from places where tap water is difficult to find, or where tap water is brackish water. For example, in Africa or Asia, where people collect water for bath from brackish wells or rivers, they also collect rain water in different container for their drinking water and cooking.

There was a research held in Australia showing that rain water is safe to drink, as long as it is collected in clean containers and properly filtered. However, since rain water contains no minerals, we should add mineral intakes if we consume rain water for more than 1 month.

Breaking The Myth

There is a myth developed in Indonesia that nobody should walk, run, or play under the rain since it can lead to fever, headache, and “trapped wind”. This is not true at all. The truth is, showering under the rain (or children like to play under the rain) does not make us sick at all. Rain water does not make us sick. The sickness is related to exposure to cold for very long time especially in cold climate, like in subtropical countries or in the mountains. Children also can get sick because of playing with their sick friends, for example when their friends already contracted common colds, flu or measles.

If we wish to shower under the rain, make sure that we do that quickly, no more than 15 minutes, then drink hot tea afterward. The same with children, it is advisable to  bath the children with warm water after playing under the rain, and after that they drink hot tea.

When touching trees or roofs before falling into water tank / container, rain water can carry dirts, algae, insect debris, even insect eggs which later develop into larvae. Therefore, we must make sure that the rain water is free of contamination. We also have to make sure that the water filter is in prime condition. Just like any water, contaminated rain water can lead to water-borne diseases like gastroenteritis.

Pregnant women should not drink rain water, except when it is already boiled or when using very good water filter. The rain water may carry some microbes like Toxoplasma, fungi or bacteria which can interfere the growth of fetus, even causing abortion.

If we happen to live in subtropical countries which do not have that much rainfall, we still can collect rain water and use it little by little.
